Validate Cluster profile - SPMD error --> Launch failed

Today I was trying to run a multiobjective optimization with the parallel option ON, as normal. But Matlab ( R2014a ) told me that parpool wasn't able to start (I am running the parallel in my computer with four cores). I check my settings for the parallel computing and they were set as they used to work last week.

Finally I went to the Cluster Profile Manager and run a test on the local cluster and it failed in the third step. This is the report:

Stage: SPMD job test (createCommunicatingJob)

Status: Failed

Description :The job errored or did not reach state finished.

Command Line Output :(none)

Error Report :(none)

Debug Log:

LOG FILE OUTPUT :

 launch failed: FAIL
 launch failed: FAIL
 launch failed: FAIL
 launch failed: FAIL

How can I fix this issue? I read form other post that re-installing Matlab would not work.

Thanks!
